I am using the REgEx "^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+[.])*(\.[a-zA-Z]{2,17})$"to validate Email but with that i am trying to resolve the MS Email Format.It satisfies all the format but i cant validate the below mentione format.

VB

Valid: js#internal@proseware.com
Valid: j_9@[129.126.118.1]

Valid Email Address :

VB

Valid: david.jones@proseware.com
Valid: d.j@server1.proseware.com

here is the code which will compare both the formats.UNfortunately i am using two loops to check the valid Email Address

C#

if (Input.match(/^[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*(\_[a-zA-Z0-9-]+)*(\#[a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+[.])*(\.[a-zA-Z]{2,17})*(\.[a-zA-Z]{2,17})$/)) {

     It will test all the formats Except IP address
    }

else if (Input.match(/^[A-Za-z0-9._%#+-]+@\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\]$/)) {
It will validate the IP address
    }

Here you can find a nice example for Email validation.
